Fe II velocity shifts in optical spectra of type 1 AGN
E. Bon, P. Marziani, M. Berton +4
Here we present a critical view of practical problems in the analysis of optical Fe II emission lines of Type 1 AGN spectra. Besides the very complex and unclear physical interpret…
Revealing the Broad Line Region of NGC 1275: The Relationship to Jet Power
Brian Punsly, Paola Marziani, Vardha N. Bennert +2
NGC 1275 is one of the most conspicuous active galactic nuclei (AGN) in the local Universe. The radio jet currently emits a flux density of Jy at mm wavelengths,…
Highly accreting quasars: The SDSS low-redshift catalog
C. A. Negrete, D. Dultzin, P. Marziani +8
The most highly accreting quasars (xA) are of special interest in studies of the physics of AGNs and host galaxy evolution. Quasars accreting at high rates (L/LEdd 1) hold p…
A multimessenger view of galaxies and quasars from now to mid-century
Mauro D'Onofrio, Paola Marziani
In the next 30 years, a new generation of space and ground-based telescopes will permit to obtain multi-frequency observations of faint sources and, for the first time in human his…
Extreme quasars at high redshift
M. L. Martınez-Aldama, A. Del Olmo, P. Marziani +5
Context:Quasars radiating at extreme Eddington ratios (xA) are likely a prime mover of galactic evolution and have been hailed as potential distance indicators. Their properties ar…
Exploring possible relations between optical variability time scales and broad emission line shapes in AGN
E. Bon, P. Jovanovic, P. Marziani +2
Here we investigate the connection of broad emission line shapes and continuum light curve variability time scales of type-1 Active Galactic Nuclei (AGN). We developed a new model…
